Five OXA-48-producing Klebsiella pneumoniae were detected in a tertiary referral hospital in Ireland between March and June 2011. They were found in the clinical isolates of five cases that were inpatients on general surgical wards. None of the cases had received healthcare at a facility outside of Ireland in the previous 12 months. This is the first report of OXA-48-producing K. pneumoniae in Ireland.

The 25 European overseas countries and territories (OCTs) are closely associated with the European Union (EU) through the four related UE Member States: Denmark, France, the Netherlands and the United Kingdom. In 2008 and 2009, these four EU Member States, in association with the European Centre for Disease Prevention and Control (ECDC), reviewed the OCTs' needs, with the objectives of documenting their capacity to prevent and respond to infectious diseases outbreaks, and identifying deficiencies. This Euroroundup is based on the review's main findings, and presents an overview of the OCTs' geography and epidemiology, briefly introduces the legal basis on which they are linked to the EU and describes the surveillance and infectious disease response systems. As a result of their diversity the OCTs have heterogeneous epidemiological profiles. A common factor, however, is that the main burden of disease is non-communicable. Nevertheless, OCTs remain vulnerable to infectious diseases outbreaks. Their capacity for surveillance, early detection and response to such outbreaks is generally limited, with laboratory capacity issues and lack of human resources. Avenues for capacity strengthening should be explored by the OCTs and the related EU Member States, in collaboration with ECDC and regional public health networks where these exist. .

Outbreaks of measles continue to occur in Italy, as in other European countries. We present here details of cases reported through the Italian enhanced measles surveillance system from July 2009 to September 2010. In total, 2,151 cases were reported, 42% (n=895) of which were laboratory confirmed. The median age of cases was 18 years and 1,709 of 1,856 cases (92%) were unvaccinated. Many cases with complications were reported (n=305), including three with encephalitis. A total of 652 of 1,822 cases (36%) were hospitalised. Molecular characterisation revealed circulation of a limited number of measles virus genotypes (D4, D8 and B3), which is consistent with the current epidemiology of the disease in Italy. A national measles elimination plan was approved in 2003 with the aim of interrupting endemic measles transmission by 2007. Since elimination was not achieved, the target date was recently moved to 2015. The emphasis of the new elimination plan, approved in March 2011, is on strengthening surveillance, implementing evidence based-interventions to increase measles-mumps-rubella vaccine uptake in children, adolescents and young adults, and implementing communication activities related to the vaccine. The strategies proposed by the plan should be implemented fully and appropriately by all regions in order to meet the elimination goal by 2015.

In Poland, a surveillance system capturing generic information on both diagnosed and undiagnosed aseptic central nervous system infections (ACI) has been in operation since 1966. This study evaluates to what extent the ACI surveillance is able to meet its objectives to monitor ACI trends and to detect signals of public health importance such as enteroviral outbreaks, tick-borne encephalitis (TBE) endemic foci, poliovirus appearance or emergence of new neurotropic viruses. Between 2004 and 2008, aetiology was established for 17% of ACI cases. Of the 1,994 reported ACI cases, 232 (11.6%) were diagnosed with TBE virus, 46 (2.3%) with enterovirus, 35 (1.8%) with herpesvirus, and 32 (1.6%) had other viral causes such as Epstein Barr virus or adenovirus. The system's performance varied between the provinces, with the frequency of suspected ACI cases referred for viral aetiology investigation in 2008 ranging from 1.98 to 285.4 samples per million inhabitants. The sensitivity of physicians' reporting, estimated as the proportion of hospitalised ACI cases reported to the surveillance system, was 48% nationally, with vast regional differences (range 30-91%). To conclude, the ACI surveillance system in Poland does currently not meet its objectives, due to limited availability of aetiological diagnosis and microbiological confirmation and to regional differences in reporting sensitivity. .
